A 19th Century view of an oil strike at oil well in Baku, Azerbaijan. By 1901, half of the world's oil was produced from 1900 wells, located within 6 square miles. Most oil production came from oil gushers in the early days, although this was a very uneconomical and environmentally-harmful process. However, the share of blowout production in the total decreased as the equipment improved. In 1898, the Russian oil industry produced more than the oil production level.
